An Experiential Investigation of Algebraic Ideas Created and Implementedby Robert B. Davis
Notice bibliographique
Résumé
Objective: To demonstrate instances of experiential learning of 6th grade students with Professor Robert Davis as the facilitator. Students first solve single order equations and then build on their learning to solve and justify the solutions of quadratic equations. Solving second order equations is generally an 8th or 9th grade strand, but through their own reflections and without intervention by the facilitator, students are able to understand the "secret" behind their solution. Description: Experiential learning is learning through reflection on doing, which is often contrasted with rote or didactic learning. Experiential learning can exist without a teacher and relate solely to the "meaning-making" (Holbrook Mahn 2012, p.101) process of the individual's direct experience. In Professor Carolyn Maher's published (1999) tribute to Professor Robert Davis two years after his passing, she quotes one of Prof. Davis' students who reflects on his own early education: "And once I had a teacher who understood. He brought with him the beauty of mathematics. He made me create it all for myself. He gave me nothing, and it was more than any other teacher has ever dared to give me." (p. 85)Reflection is a crucial part of the experiential learning process and Dewey wrote that "successive portions of reflective thought grow out of one another and support one another." (Kompf & Bond 2001 p. 55) Robin Alexander reinforced this idea when he wrote about creating a scaffold for further learning, and allowing for further experiences and learning. (2010)Facilitation of experiential learning is challenging, but a skilled facilitator asking the right questions and guiding reflective conversation before, during and after an experience, can help open a gateway to powerful new thinking and learning. The analytic is drawn from a set of 11 clips of Early Algebra of 6th grade students as Prof. Davis introduces the ideas of a variable, truth statements and legal substitutions. Students solve first order equations and with this experience they are able to solve second order equations; all without direct assistance from Prof. Davis. Finally individual students discover the "secret" for solving a special set of second order equations and since it is a secret all students are given the opportunity to arrive at a conjecture. No students are told the answer as they use their own experience to create justification.In conclusion I could not have produced this analytic without the long hours of editing video in the VMC by Kathy Spang and Patty Giordano.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
